Kaṭha Upaniṣad · 1.2.11
यत्र मेधावी वृद्धिमिच्छन् विद्वान् हृदयस्य ब्राह्मणः । स नः संसारमायातु प्रतिवोत प्रतिवोऽव्ययः ॥
yatra medhāvī vṛddhimicchan vidvān hṛdayasya brāhmaṇaḥ | sa naḥ saṃsāramāyātu prativoto prativo'vyayaḥ ||
Where the priest of the heart, the wise one desiring growth, attains plenitude. May He, the indestructible, guide us from this samsara, from darkness into light.
The brāhmaṇaḥ hṛdayasya (priest of the heart) is a metaphor for the Ātman as celebrant of the interior sacrifice. The heart is the altar where everything is offered — thoughts, emotions, actions — to the fire of consciousness. The medhāvī (intelligent one, sacrificer) is one who performs this internal yajña.
Vṛddhim icchan (desiring growth) indicates that spiritual progress is continuous. The vidvān (knower) is never satisfied with partial achievements; always seeks complete fullness (pūrṇatā). This attitude of constant growth is essential — complacency is the enemy of the sādhaka.
The final invocation is a praṇāma (reverence) and request for guidance. Saṃsāram āyātu — may He guide us from this cycle of existence. The avyayaḥ (indestructible, immutable) is one who can liberate us because He Himself is never subject to change. Only the eternal can grant eternity.
Prativoto (responding, guiding) suggests that this guidance is not coercive but responsive to the seeker’s call. The divine does not impose salvation but responds to sincere effort. This is the dynamic of grace (prasāda) in yoga — human initiative invokes divine response.
